If by "prevalent" you mean installed capacity, then wind far outstrips solar. Latest numbers I saw were 238 GW for wind, 67 GW for solar. You also mention solar efficiency of 19% (that is a typical number for panels themselves) and then say we need 95% to "maximize use of harvested solar energy". I think you probably meant to say that just the inverter efficiency should target 95% since basic physics limits existing Si panel efficiency to about half that.

At a systems level, if you have any electrical storage in the system, you are best off to connect the panels and the batteries by DC, not AC. That typically results in 10% more energy available when you invert the AC out of the storage. (1. Eliminates a conversion: DC -DC - AC instead of DC - AC - DC - AC, and 2. higher end-to-end efficiency)

Microsmi makes vry lo pwer FPGA device.
Misleading is the use of 1t,2nd,srd for efficiencyimprovements
the are all seperate and inependent issues.
MPPT input power otimization.
PWM, how any MPPT, PFC, PFM or PWM circuit works, it s the basis of all modern power conversion.
PFC = current propotionl to voltage... over fundamental period.
All must be used together to maxamize efficiency.
